MEMS VOA is a precise and adjustable voltage-driven optical component. The key part of the component is MEMS chip; driving voltage produces electrostatic force to drive the micro-mirror on the chip, then to adjust output optical power. It has excellent features such as compact dimension, low power consumption, fast responding, anti-shock, low WDL as well as low PDL. It is successfully applied in military project. It meets reliability standard of Telcordia 1221.MEMS VOA has 2 series: fast responding series and low voltage driving (LOWO) series. Each series has variable models like single wavelength, dual wavelength, and polarization-maintaining.We could also develop and produce other MEMS VOA as customers' requirement.
MEMS VOA is based on a micro-electro-mechanical system. Inside the MEMS VOA, a MEMS chip with a tilting mirror on the silicon is seated and wire bonded to the pins. A voltage applied to MEMS chip can causes the mirror to rotate, which changes the coupling of light between the input fiber and output fiber, thus the desired attenuation amount. MEMS VOA achieves highly repeatable optical attenuation over C or L Band. It gives Soloreinâ??s VOA an advantage in WDM, VMUX/DEMUX, EDFA and optical network protection applications.

PROTOCONTROL offers Signal Isolators to isolate and convert field signals like resistance, current, voltage, frequency to 4-20 mA. These isolators find use in process control industries for signal isolation. Variety of models is available for specific applications.
Transmitters are the field devices which receives signal from field sensors like temperature sensor (Pt 100, thermocouple) or load cell & convert these in suitable form like 4-20mA, O-20 mA, 0-10V as an input for panel instruments.
In the field, many signals are generated such as motor current, armature voltage, position feedback in the form of change in resistance or signals obtained from various types of traducers in standard voltage or current form. These signals are not isolated from input and not suitable for transmission over long distance. Converters are specially developed to overcome these problems in transmission such as line drop, interference, ground looping, and non compatibility to standard processing unit.
Salient features includes complete galvanic isolation between input output and control supply , Independent zero and span adjustments ,Stable current output eliminates need for special cable, shielding,
The isolators are housed in din rail mounting engineering plastic enclosure. Special robust cast Al. enclosures suitable for field mounting are also available.
These Isolators are extensively used in cement, fertiliser, chemical, and processing plants.
